Installation & Placement 

 

The 

LAB12 HPA

 should be placed on a solid flat surface.  

You should avoid placing it near a heat source as this could compromise the HPA performance and reliability. Due 
to tubes design, HPA chassis could be hot so you should never place another component directly on top of this 
device

.  Make sure the device has enough space to ventilate. 

 Take care of the finest luxury finish of front panel with a soft cloth.
